TO,- ALL WHOM I T MAY CON CERN:

Bc it known that I, HOBART G. ARNOLD., of Rochester, inthe county of Monroe, and State of New York, have invented new andpseful Improvements in a Fastener or Loekfor Window-Sash, of which the followingis a full and exact description, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked` thereon; and of said drawings#- I Figure 1 is a perspective view .of the lock as applied to the sash, and let in even with the face of it, which is. the most common way of applying, with the holt extended downward and outward, showing its positidn when the sash is locked'. Letter I represents a slot or opening inthe box for the nib A, by which the loch is worked.

Figure 2 represents the nib drawn inward,iwith the bolt and tumbler, hereinafter described, showing their position when the sash is unlocked. The downward motion is by their own weight.

Figure 3 represents the nibunoved to the'left hand, and into the notch'D. which secures it in that position, I

leaving the sash unlocked any length of time desired.

Figure 11 is an inside view ofV the lock, with the b clt ,p'artly drawn up. The tumbler i's between the box and bolt, so that it cannot be seen. i v

Figure 4 represents the tumbler by which the lock 'is operated, and locked upward or downward, parts of which are shown in figs. 1, 2, and 3f.

Figure 5 isa lateral view of the tumbler.

Figure 7 is a separate viewoil the bolt.

Figure 6 is a lateralview of the same, f

Figure 8 is a view of the bolt and tumbler. The latter is hereilet in even, but not necessarily, and they are secured together loosely by a pin.' i

Figure 9 represents the same drawn upwards, as shown in g; 3.

Figure 10 is an inside view of the box.

Letter B represents the notch into which the tumbler drops when it is down, and holds it there, so that the bolt cannot be rased'or moved inward by any pressure upon the outer end of it. The dotted lines here given represent the position of the tumbler Gr when it falls into -notch B.

The nature of my inventionl consists in so constructing and arranging a box, holt, and tumbler, that they may be operated by a nih or handle on the tumblerfthe latter so arranged that, at the pleasure of th'e person operating, it may hold the bolt inward and upward, leaving'the sash unlocked and free, so that both hands may bc used in raising or lowering it; or it may be left in this positionfor any length of time desired, which vis often very desirable., and particularly in lweighted sash, the natural movement of the bolt and tumbler being free in their upward and downward motion the sameas though they were not intended to be locked upward; also that, when desirable, the same tumbler may be made so vas to lock the holt down, as shown in iig. 10,`with out materially affecting the movement ofthe nib in its upward and downward motion by the hand or the' weight of ,the bolt and tumbler. But :is-this is intended onlyas additional securityto the bolt when locked, it is not absolutely necessary, so that thelock may be made with or without it, without affecting the validity of the patent. "i

Toenable others skilled in the art to ina-lie and use Lny invention, I refer again to the drawings, which are intended to be full size, or any other size may be selected, as desired. s I

The holt and tumbler should be sullciently loose to work freely, '.lh outside form of tlie'box as here sho'wn is intended for economy irl-manufacturing, land for convenience in applying it to the sash. lBy referring to fig. 8 it will be seen, as there shown, the tumbler inclines to the right, so that it is not affected by notch D,

and, when down, naturally falls into notch B, holding the bolt securely against any pressure that may be brought to bear upon the outer end of it. Neither is'it affected by notch B in raising it upward with the. hand, provided the hand is moved perpendicular-ly, or nearly so; but when the nib is movedl into .notch D, .as shown in iig 3, the tumbler inclines to the left, which, with the form of the notch, holds the bolt up, leaving the sash unfastened, so that both hands may be used i'n raising or lowering it; or it may be left in that position any length of time desired. It will be seen that it requires but a slighteifort to move the nib into notch D, or to remove it into its natural position, es shown inffigs. l, 2, and S.

,To make the loeli for right hand, it will'only be necessary to reverse the patterns accordingly, as seenvin `Figure 12. This arrangement allows of a longer box, better adapted to variations of the upper endJ so as to accommodate the different widths of sash or thicknesses of moulding, consequently :Honger and heavier bolt, giving a stronger motion downward without increasing the weight or expense of the lock. But the lock is nel: 'necessarily confined to the shape here given, butnmy be varied es desired. v

Having thus fully described my invention and its utility, what claim as new, and wish to secure by Letters'Petent, is- A sash-look, composed of bolt H, tumbler G, and notched plate, 'che whole combined and arranged subsentially as and for the purposes set forth.

HOBART G. ARNOLD.
